Why am I getting "Error 429 TOO MANY REQUESTS" when making API calls to Pressero?

PRESSERO > *Pressero FAQs
It means that you are making too many API calls in a short period of time to our API. If your application makes more than 10 requests in 10 seconds to the Pressero API from your public IP address, this error will be shown. 
If you see that your application is not making this many requests to Pressero, you may want to check that your account is not also running the Automated Workflow Integrator in addition to the API. That could be causing more requests than expected to happen from your public IP address.
